Among (or amongst) and between (or betwixt) have a difference in meaning, and usually a difference in use. Among originally meant in the crowd (on gemong), referring to several objects; between and betwixt were originally made up of the preposition be (meaning by) and twēon or twēonum (modern twain), by two, and be with twīh (or twuh), having the same meaning, by two objects.
As to modern use, see "Syntax" (Sec. 459).
PREPOSITIONS OF TIME.
314. They are after, during, pending, till or until; also many of the prepositions of place express time when put before words indicating time, such as at, between, by, about, on, within, etc.
These are all familiar, and need no special remark.
EXCLUSION OR SEPARATION.
315. The chief ones are besides, but, except, save, without. The participle excepting is also used as a preposition.
MISCELLANEOUS PREPOSITIONS.
316. Against implies opposition, sometimes place where. In colloquial English it is sometimes used to express time, now and then also in literary English; for example,—
She contrived to fit up the baby's cradle for me against night.—Swift
